关于平方、立方和高次幂的Waring-哥德巴赫问题

On Waring-Goldbach Problem for Squares, Cubes and Higher Powers

Min Zhang, Jinjiang Li

摘要:

令$\mathcal{P}_r$表示一个几乎素数,至多有$r$素因子,根据重数计数。本文推广了Vaughan关于三元容许指数的结果.此外,我们使用改进的容许指数来证明,对于$3\leqslant k\leqslant 14$和对于每个足够大的偶数$n$,下面的方程\begin{equation*} n=x^2+p_1^2+p_2^3+p_3^3+p_4^3+p_5^k \end{equation*}是可解的,其中$x$是几乎素数$\mathcal{P}_{r(k)}$和其他变量素数,其中$r(k)$在定理中定义。这一结果是对以往结果的深化。

英文摘要:

Let $\mathcal{P}_r$ denote an almost-prime with at most $r$ prime factors, counted according to multiplicity. In this paper, we generalize the result of Vaughan for ternary admissible exponent. Moreover, we use the refined admissible exponent to prove that, for $3\leqslant k\leqslant 14$ and for every sufficiently large even integer $n$, the following equation \begin{equation*} n=x^2+p_1^2+p_2^3+p_3^3+p_4^3+p_5^k \end{equation*} is solvable with $x$ being an almost-prime $\mathcal{P}_{r(k)}$ and the other variables primes, where $r(k)$ is defined in Theorem. This result constitutes a deepening upon that of previous results.
